AN EXAMINATION OF THE EMPIRICAL PROPERTIES OF DUALITY BETWEEN THE RESTRICTED PROFIT, UNRESTRICTED PROFIT, AND PRODUCTION FUNCTIONS AgEcon
Lusk, Jayson L.; Abdulkadri, Abdullahi O.; Featherstone, Allen M..
This research examines the empirical properties of duality theory. A comparison of the Hessian matrices calculated from the normalized unrestricted and restricted profit, and production functions indicate that duality is highly sensitive to measurement error and relative price variability. Keywords: duality, restricted and unrestricted profit functions
Tipo: Conference Paper or Presentation Palavras-chave: Duality; Restricted and unrestricted profit functions; Demand and Price Analysis; Production Economics.

Economies of Scale in the Floriculture Industry AgEcon
Schumacher, Sara K.; Marsh, Thomas L..
This study investigated the cost structure of the floriculture industry in the United States. Economies of scale and input elasticities were estimated with a normalized quadratic cost function. Results suggest that economies of scale exist in the floriculture industry. As producers become large and more automated, they have a cost advantage relative to smaller producers who are producing the same output product mix. The existence of economies of scale suggests that average grower size can increase in the future as growers increase in size to take advantage of cost efficiencies.

Estimating Indirect Production Functions with a More General Specification: An Application of the Lewbel Model AgEcon
Hilmer, Christiana E.; Holt, Matthew T..
Whereas consumer theory employs several different empirical specifications for estimating indirect utility functions, producer theory has relied on the Translog specification to estimate the indirect production function. In this paper, we apply Lewbel’s more general functional specification and investigate its implications for the estimation of indirect production functions in productivity analysis. An attractive feature of the Lewbel model is that it nests both the Translog and the almost ideal supply system, offering a method to assess the empirical validity of all three specifications. Aggregate U.S. production data are used to examine the performance of the three models in an empirical application.

Measuring Social Welfare: A Dog’'s Hind Leg Possibility Postulate AgEcon
Hertzler, Greg.
Our current methods of analysing policies and the distributions of wealth insure that society is on an efficient frontier. This is not the same as a social optimum. To choose the optimal point on the frontier we need a social welfare function. Following the ordinal revolution in demand theory, a large body of research concluded that social welfare functions don't exist. The intensity of people's preferences cannot be observed and hence interpersonal comparisons are essentially impossible. This paper argues that the intensity of people's preferences can be observed and could be incorporated into a social welfare function.

Production Risk and the Estimation of Ex Ante Cost Functions AgEcon
Moschini, GianCarlo.
Cost function estimation under production uncertainty is problematic because the relevant cost is conditional on unobservable expected output. If input demand functions are also stochastic, then a nonlinear errors-in-variables model is obtained and standard estimation procedures typically fail to attain consistency. But by exploiting the full implications of the expected profit maximization hypothesis that gives rise to ex ante cost functions, it is shown that the errors-in-variables problem can be effectively removed, and consistent estimation of the parameters of interest can be achieved. A Monte Carlo experiment illustrates the advantages of the proposed procedure as well as the pitfalls of other existing estimators.
Tipo: Working or Discussion Paper Palavras-chave: Cost function; Duality; Expected profit maximization; Nonlinear errors-invariables; Stochastic production; Risk and Uncertainty.
